The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

To assist in understanding aspects of embodiments of the present application, related concepts that may be referred to herein are briefly described as follows:

(one) deactivating SCG

In a multi-connection scenario, it is divided into one primary cell group (Master Cell Group, MCG) and one to more secondary cell groups (Secondary Cell Group, SCG). The Cell group at the Master Node (MN) side is a Master Cell group, and is composed of one Primary Cell (PCell) and zero to a plurality of Secondary cells (scells). The Secondary Node (SN) side cell group is a Secondary cell group, and also one SCG is composed of one primary Secondary cell (Primary Secondary Cell, PSCell) and zero to multiple Secondary cells scells. The current protocol version only supports the dual connectivity scenario. In the connected state, the UE is configured with double connection, and the MN and the SN can simultaneously perform data interaction with the UE.

Considering energy saving and rapid activation of SCG for data transmission, the UE may set the SCG side to a deactivated SCG state in which the UE does not monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH) of the SCG side and does not transmit the physical uplink shared channel (Physical Uplink Share Channel, PUSCH) in the case that the data transmission amount is small.

(II) activation/deactivation of SCG

The MN/SN/UE may request activation of the SCG, and a network triggered SCG activation command is sent by the MN to the UE. The MN/SN may request that the SCG be deactivated and a network-triggered SCG deactivation command is sent by the MN to the UE. In the SCG activation/deactivation process, RRC signaling is used for interaction between UE/MN and MN/SN.

When the SCG is deactivated, all timing advance timers (Timing Advance Timer, TAT) on the SCG side continue to run, and in the SCG deactivation state, if the TAT times out, a random access channel (Random Access Channel, RACH) procedure is not performed. In the SCG deactivated state, the UE may perform radio resource management (Radio Resource Management, RRM) measurements, and may perform beam failure detection (Beam Failure Detection, BFD)/radio link monitoring (Radio Link Monitoring, RLM) based on network configuration. In the deactivated SCG state, all SCG SCells are in the deactivated state.

Fig. 1 is one of flow diagrams of a method for processing SCG status information provided in an embodiment of the present application, as shown in fig. 1, where an execution body of the method for processing SCG status information is a terminal, and the method includes:

step 101, receiving an SCG processing instruction sent by network side equipment;

Step 102, based on the SCG processing instruction, adjusting the state of the SCG to a first state, and recording state information of the SCG in the first state.

Specifically, at present, the terminal UE supports a dual-connection scenario, generally a master node MN and an auxiliary node SN, where both MN and SN are connected to a Core Network (CN), that is, when the terminal UE is configured with a master cell group MCG and an auxiliary cell group SCG by the Network, the terminal UE is called dual-connection (Dual Connectivity, DC), and if there may be one or more auxiliary nodes SN, the corresponding terminal UE is in a multi-connection scenario when the terminal UE connects a plurality of auxiliary nodes SN. The MCG contains one or more cells, which are the first cell group to which the UE is connected; the MCG includes a primary cell PCell and a secondary cell SCell, where cells in the primary cell group except the primary cell are called secondary cells, and the primary cell is the first cell to which the terminal UE is connected in the MCG. The SCG comprises one or more cells, and is an added secondary cell group SCG after the UE establishes connection with the MCG, wherein the first cell connected with a terminal in all cells in the SCG is called a primary secondary cell PScell. Cells within the secondary cell group other than PSCell are also referred to as scells.

When the terminal is in a multi-connection scenario, the network side device may send an SCG processing instruction to the terminal according to service requirements, so that the terminal adjusts the state of one or more connected SCGs, or the state of one or more to-be-connected SCGs is a first state, where the first state may be an active state, a deactivated state, an idle state, a connected state, etc., and is adjusted to different states according to different service requirements, and the terminal records relevant information of state adjustment of each SCG. The state adjustment information of the specific recorded SCG may be various, for example: the state of SCG before, the time information consumed by the state is adjusted, whether the beam failure is detected or the radio link failure is detected in the state adjusting process, etc.

The above-recorded relevant information of the state adjustment of the SCG may be saved in the form of a new report, or recorded in the UE movement history information on the existing SCG side, or recorded in other existing reports, etc.

According to the SCG state information processing method, under the multi-connection scene, the SCG state related information is recorded and reported to the network side, so that the network side can conveniently know the SCG state change, judge whether the PScell of the SCG side is synchronous with the uplink and downlink of the network side or not, and the like, and further, the network side can be assisted to optimize the activation or deactivation decision and related configuration of the SCG.

Specifically, when the terminal is in a multi-connection scenario, the state of the SCG to which the PSCell currently accessed by the terminal belongs is an active state, and the PSCell and the SCG have a one-to-one correspondence relationship, and the terminal can determine the SCG to which the PSCell belongs according to the PSCell currently accessed. The currently accessed PSCell may be a target PSCell after terminal handover, where the target PSCell is a PSCell reconfigured by a network side, and an SCG to which the PSCell belongs is in an active state, or may be a source PSCell, i.e. a PSCell that is normally connected. At this time, the terminal has no service requirement, or takes energy saving into consideration, the network side sends an SCG deactivation instruction to the terminal through the main node MN or the auxiliary node SN, the terminal receives the instruction, deactivates the SCG, and records the state information of the SCG at the terminal side, thereby being beneficial to the network side to know the state change of the SCG, judging whether the PScell at the SCG side is synchronous with the downlink or uplink DL/UL of the network or not, and further being capable of assisting the network side to optimize the activation or deactivation decision and relevant configuration of the SCG.

Similarly, when the state of the current PSCell to which the terminal is connected or the SCG to which the PSCell to be connected belongs is a deactivated state, the PSCell to be connected refers to a target PSCell to which the terminal needs to be switched, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in the deactivated state. At this time, since the SCG to which the target PSCell belongs is in a deactivated state, the UE does not immediately perform random access to the target PSCell. When the network side has new service requirements for the terminal and the SCG is in a deactivated state, the terminal does not monitor the PDCCH at the SCG side and does not transmit the PUSCH. It is necessary to activate the SCG to which the PSCell currently accessed by the terminal belongs as soon as possible, or activate the SCG to which the PSCell to be accessed belongs as soon as possible, and randomly access the PSCell to be accessed. The method is favorable for the quick recovery or establishment of the data transmission channel, thereby carrying out new service or data transmission. Therefore, the network side sends an SCG activation instruction to the terminal through the master node MN or the slave node SN, the terminal receives the instruction, activates the SCG, and records the state information of the SCG at the terminal side.

The specific status information for recording that the SCG is in the first state may be various, for example: under the condition that an SCG activation instruction is received, recording whether the state of the SCG is an activation state or a deactivation state, and whether beam failure or radio link failure is detected in the process of activating the SCG. Under the condition that an SCG deactivation instruction is received, recording whether the state of the SCG is an activated state or a deactivated state, and whether beam failure or radio link failure is detected in the process of deactivating the SCG.

The above SCG activation instruction and SCG deactivation instruction may be sent by the primary node MN or the secondary node SN in the network device.

Optionally, the state information of the SCG includes any one or more of:

PSCell identification of SCG;

first indication information for indicating that the SCG is in a first state;

the number of times the SCG is in the first state;

time information that the SCG is in the first state;

third indication information for indicating whether beam failure is detected;

wherein the first state is an activated state or a deactivated state.

Specifically, the terminal may record the state information of the SCG by any one or a combination of the following ways:

1. the PSCell identifier of the SCG, that is, the PSCell identifier currently accessed by the terminal or PSCell identifier information to be accessed.

In a multi-connection scene, the terminal is connected with one PSCell, the state of the SCG to which the PSCell belongs is an activated state, when the terminal has no service requirement or in order to save energy, the network side can send an SCG deactivation instruction, and in the process of deactivating the SCG, the terminal records the currently accessed PSCell identifier, or the PSCell identifier to be accessed, and the PSCell identifier and the SCG have a one-to-one correspondence relationship, so that the PSCell is deactivated, namely the SCG to which the PSCell belongs is set to be in a deactivated state. For a general SCG deactivation instruction, that is, the deactivation instruction is not accompanied by a synchronous reconfiguration command, then the UE records the PSCell ID currently accessed, and for an SCG deactivation instruction sent to the UE together with the synchronous reconfiguration command, that is, when the state of the SCG to which the target PSCell belongs is configured to be in a deactivated state, then at this time, the UE may record the source PSCell ID or the target PSCell ID, for example: and indicating the SCG state as the SCG deactivation state in the received synchronous reconfiguration command, and recording the target PSCell ID.

When the terminal is connected or is to be accessed into a PSCell, and the state of the SCG to which the PSCell belongs is a deactivation state, a new service or data transmission requirement exists, and the network side sends an SCG activation command, the terminal records the identification of the currently accessed PSCell in the SCG activation process, and the PSCell identification and the SCG have a one-to-one correspondence relationship, so that the PSCell is activated, namely the SCG to which the PSCell belongs is set to be in the activation state. For a common SCG activation instruction, the SCG activation instruction is not sent together with a synchronous reconfiguration instruction, and then the terminal needs to determine whether a target PSCell to which the terminal needs to be switched is reconfigured by the network side before receiving the SCG activation instruction, and the SCG to which the target PSCell belongs is in a deactivated state. If the target PSCell is reconfigured by the network side before and the SCG to which the target PSCell belongs is in a deactivated state, activating the target PSCell after receiving the SCG activation instruction, and recording the target PSCell identifier; if the target PSCell is not reconfigured at the network side before and the SCG to which the target PSCell belongs is in a deactivated state, after receiving the SCG activation instruction, activating the SCG to which the PSCell currently accessed by the terminal belongs, namely setting the SCG to which the PSCell currently accessed by the terminal belongs as an activated state. If the SCG activation instruction and the synchronous reconfiguration instruction are sent together, the synchronous reconfiguration instruction configures a target PSCell, the terminal accesses the target PSCell, and records the target PSCell identification.

The PSCell identification may be represented by a form of PSCell ID, and the PSCell ID may be represented by a physical cell identification (Physical Cell Identifier, PCI) and a frequency point, or a global cell identification (Cell Global Identifier, CGI).

2. And the first indication information is used for indicating that the SCG is in a first state.

The indication information indicates that the state of the SCG to which the PSCell connected to the terminal belongs is a deactivated state or an activated state, or that the state of the SCG to which the PSCell to which the terminal is to be connected belongs is a deactivated state, and may be recorded in different forms, for example, in the form of an entry, the SCG state is indicated to be the deactivated state in the one entry, and the entry is used for recording the relevant information of the SCG deactivation process.

3. The number of times that the SCG is in the first state, that is, the number of times that the SCG state to which the PSCell to which the terminal is currently connected or the PSCell to be connected belongs is in an activated state or in a deactivated state.

Recording the number of times that the SCG state of the PScell is changed into a deactivated state when the terminal keeps connecting with the currently accessed PScell under the condition that the terminal receives an SCG deactivation instruction or keeps connecting with the PScell to be accessed in the process of determining the PScell to be accessed; or when receiving the SCG activation instruction, the terminal changes the SCG state of the PScell into the activation state in the process of keeping the current access to the PScell. The currently accessed PSCell may be a target PSCell after terminal handover, where the target PSCell is a PSCell reconfigured by a network side, and an SCG to which the PSCell belongs is in an active state, or may be a source PSCell, i.e. a PSCell that is normally connected.

4. The time information of the SCG in the first state, namely the time information of the SCG which belongs to the PSCell currently accessed by the terminal or the PSCell to be accessed in the specific state; wherein the specific state is an activated state or a deactivated state.

Recording specific time information of the SCG of the PSCell currently accessed by the terminal or the PSCell to be accessed in a deactivated state under the condition that the terminal receives an SCG deactivation instruction; or the specific time information that the SCG to which the PScell currently accessed by the terminal belongs is in an activated state when the terminal receives the SCG activation instruction. The currently accessed PSCell may be a target PSCell after terminal handover, where the target PSCell is a PSCell reconfigured by a network side, and an SCG to which the PSCell belongs is in an active state, or may be a source PSCell, i.e. a PSCell that is normally connected.

5. And second indication information, configured to indicate whether the timing advance timer TAT times out, i.e. whether the TAT times out each time the SCG is activated or each time the SCG is in a deactivated state.

Recording whether a terminal accesses a PSCell or a PSCell to be accessed belongs to SCG in a deactivating state or not when receiving an SCG deactivating instruction; or if the terminal receives the SCG activation instruction, when the SCG to which the PScell connected by the terminal belongs is activated each time, the TAT corresponding to the SCG is overtime.

6. And third indication information, configured to indicate whether a beam failure is detected, that is, whether a beam failure is detected each time the SCG is activated or each time the SCG is in a deactivated state.

Recording whether the terminal receives a SCG deactivation instruction or not, and judging whether the terminal accesses a PSCell or whether the PSCell to be accessed belongs to the SCG in a deactivation state or not; or if the terminal receives the SCG activation instruction, the terminal detects the beam failure when the SCG to which the PScell connected by the terminal belongs is activated each time.

7. Fourth indication information, which indicates whether a radio link failure is detected, i.e. whether a radio link failure is detected each time the SCG is activated or each time the SCG is in a deactivated state (Radio Link Failure, RLF).

Recording whether a Radio Link Failure (RLF) is detected or not by a terminal in the process that the terminal receives an SCG deactivation instruction and the PSCell accessed by the terminal or the SCG to which the PSCell to be accessed belongs is in a deactivation state each time; or if the terminal receives the SCG activation instruction, the terminal detects the radio link failure RLF when the SCG to which the PScell connected by the terminal belongs is activated each time.

According to the SCG state information processing method, under the multi-connection scene, specific relevant information of the SCG in the activated state or the deactivated state is recorded, and the specific relevant information of the SCG state is reported to the network side, so that the network side can know SCG state change more clearly, whether the PScell of the SCG side is synchronous with the uplink and the downlink of the network side or not can be judged accurately, and the network side can be assisted to optimize SCG activation or deactivation decision and relevant configuration.

Optionally, the state information of the SCG includes any one or more of:

state information for indicating the state of the SCG to which the terminal belongs when the terminal accesses the SCG for the first time;

for indicating that the SCG was in a first state;

the SCG maintains the total duration of the first state.

Specifically, the state information of the SCG recorded by the terminal includes any one or more of the following:

the state information indicates the state of the SCG when the terminal is accessed to the SCG for the first time, namely indicates that the state of the SCG to which the PScell belongs is in a deactivated state or an activated state when the terminal is accessed to the PScell or to be accessed to the PScell for the first time; the state of the SCG may be different from or the same as the first state of the received processing instruction after the SCG state is adjusted. Mainly consider that when the terminal receives the SCG deactivation command, if the SCG deactivation command is sent to the UE together with the synchronization reconfiguration command, the UE may record the target PSCell ID configured in the synchronization reconfiguration command, and record the SCG state when accessing this PSCell as the SCG deactivation state, for example: indicating that the SCG state when accessing the PScell is an SCG deactivation state; when the terminal receives the SCG activation instruction, if the SCG activation instruction is sent to the UE together with the synchronization reconfiguration command, the UE may record the target PSCell ID configured in the synchronization reconfiguration command, and record the SCG state when accessing the PSCell as the SCG activation state, for example: indicating that the SCG state when accessing the PScell is an SCG activation state; the PSCell to be accessed by the terminal mainly refers to a target PSCell configured through a synchronous reconfiguration command;

An indication message, which indicates that the SCG is in a first state, that is, indicates that the state of the SCG to which the PSCell belongs is in a deactivated state or an activated state in the process of accessing the PSCell by the terminal; when the terminal receives the SCG deactivation instruction, during the process of accessing a PSCell, if the SCG to which the PSCell belongs is in a deactivated state, no matter how many times the SCG has been changed to the deactivated state during the process, only one indication information is recorded to indicate that the SCG is deactivated, for example: this indication is true, which indicates that in the process of accessing this PSCell, the SCG to which the PSCell belongs is in a deactivated state; when the terminal receives the SCG activation instruction, that is, when the UE accesses a PSCell, if the SCG to which the PSCell belongs is in an activated state, no matter how many times the SCG is changed to the activated state in the process, only one indication information is recorded to indicate that the SCG is activated, for example: this indication is true, indicating that SCG was activated during access to this PSCell;

When the terminal receives the SCG activation instruction, in the process that the terminal keeps connecting with one PSCell, the total duration of the SCG to which the PSCell belongs in the activated state, for example: in the PSCell process, the SCG to which the PSCell belongs is in an activated state twice, the duration is 1.5ms and 2ms respectively, and the total duration of the SCG to which the PSCell belongs in the activated state is 3.5ms.

Optionally, the time information includes any one or more of:

Specifically, when the terminal receives an SCG deactivation instruction sent by the network side, in the process that the SCG is in a deactivated state each time, or in the process that the SCG is received and an activation instruction sent by the network side is received, if a beam failure is detected each time when the SCG is activated, information related to the beam in which the beam failure occurs is also required to be recorded, including a beam identifier and a beam measurement result in which the beam failure is detected each time, and if multiple beam failures exist in the deactivation process, the beam identifier and the beam measurement result in which the beam failure occurs each time can be recorded in a list form.

the number of beam failure recovery;

the number of beam failures that occur.

Specifically, when the terminal receives the SCG deactivation instruction, during the SCG deactivation process, the terminal records the indication information of whether the current beam failure is recovered successfully, for example: the indication information of a certain time is true, which indicates that the beam failure recovery is successful, the indication information of a certain time is false, which indicates that the beam failure recovery is unsuccessful, and the indication information of whether the beam failure recovery is successful or not each time can be recorded in a list mode. In addition, the number of beam failure recovery can be recorded, and the number of beam failure recovery can also be recorded in a list mode. And the indication information indicates that the beam failure recovery is successful for a certain time or a certain times, and the corresponding record is recorded with the beam identification and the beam measurement result recovered when the recovery is successful each time. In the case of multiple successful recovery, the beam identity and beam measurement results for each successful recovery may be recorded in the form of a list.

In addition, the number of beam failures occurring during each time the SCG is in the deactivated state may also be recorded. When the terminal receives the SCG deactivation command, the terminal records the number of times of beam failure occurring in the present deactivation process each time when beam failure is detected in the SCG deactivation process, for example, the number of times of beam failure occurring in the present deactivation process is 3, and the number of record bars of the beam identification and the beam measurement result of each time of beam failure detected is the same as the number of times of beam failure occurring in the record when beam failure is detected.

The cause of the radio link failure;

the number of radio link failure recovery;

the number of radio link failures that occur.

Specifically, when the terminal receives the SCG deactivation command, the terminal needs to record related information about the occurrence of the radio link failure when detecting the radio link failure in the SCG deactivation process, including one or more of the following:

reasons for radio link failure, such as: the reason for this radio link failure is that T310 times out, and in the SCG deactivation process, the number of times of radio link failure may be multiple, and the reason for each radio link failure is recorded in the form of a list.

The number of radio link failure recovery, such as: in case a radio link failure is detected, how many times a radio link failure recovery is performed, whether or not it is successful, is recorded.

Sixth indication information for indicating whether or not the radio link failure recovery is successful, i.e., indication information indicating whether or not each radio link failure recovery is successful, such as: the indication information of the radio link failure recovery is true, which indicates that the radio link failure recovery is successful, the indication information of the radio link failure recovery is false, which indicates that the radio link failure recovery is unsuccessful, and in the process of the SCG deactivation, multiple radio link failures may exist, and the indication information of whether the multiple radio link failure recovery is successful is recorded in a list form.

The number of radio link failures occurs, that is, how many times the terminal has occurred in the process of SCG deactivation under the condition that the terminal receives the SCG deactivation instruction.

Specifically, when the terminal receives the SCG deactivation command, and when the terminal detects the radio link failure in the SCG deactivation process, the terminal needs to record the related information of the occurrence of the radio link failure, and the method further includes:

the terminal records how many times the radio link failure occurs during the SCG deactivation process, i.e. the number of times the radio link failure occurs during the SCG deactivation process, for example: the number of radio link failures occurring during this deactivation is 2. The corresponding number of records that record the cause of each radio link failure is the same as the number of records.

an activation manner used when SCG is activated, the activation manner including: a random access channel RACH mode or a non-random access channel RACH procedure mode;

the value of TCI state configured at the network side.

Specifically, when the terminal receives the SCG activation instruction, that is, the first state is the activated state, the state information of the SCG further includes any one or more of the following:

recording the activation mode used in the activation of SCG includes: a random access channel RACH mode or a random access channel RACH procedure mode (i.e., RACH-less mode), for example, if the network side configures an indication terminal to use RACH mode, the terminal uses RACH mode to access, if the network side does not configure an indication terminal to use RACH mode, the terminal determines whether the condition of itself satisfies the condition of RACH-less mode access, such as whether TAT is overtime or invalid, whether beam failure is detected, or whether radio link failure is detected, if the terminal satisfies the condition, that is, the TAT has no overtime or invalid, beam failure is not detected, or radio link failure is not detected, RACH-less mode access is adopted, and if the terminal cannot satisfy the condition of RACH-less mode access, RACH mode access is adopted.

Indication information for indicating that TAT is running and invalid. The network side can learn that when the terminal UE receives the SCG activation command to activate the corresponding SCG according to the indication information, the TAT is running, but the terminal and the network are already out of step in the uplink at this time.

Indication information for indicating whether the network side is configured with a transmission configuration indication state TCI state, for example: this indication is true, indicating that the network has configured a TCI state in the SCG activate command when the SCG is activated.

When the terminal receives the SCG activation instruction and the network side configures the TCI state, the SCG state information recorded by the terminal further comprises:

the TCI state value configured by the network side when the SCG is activated, i.e. the TCI state value configured by the network is recorded. The network side receives the value of the TCI state configured at the time and other auxiliary information related to SCG activation, and can know whether the value of the TCI state configured at the time is proper.

The above state information of the SCG includes active state record content and inactive state record content, and may be recorded in the same report or may be recorded in two reports respectively.

After the terminal records the state information of the SCG, an available indication can be reported to a network side, and the network acquires the state information of the SCG recorded by the terminal through a UE information process. Such as the UE reporting an availability indication to the MN or SN. The MN or the SN requests the UE to report the recorded SCG state information through the UEInformationRequest message; the terminal UE reports the recorded SCG state information to the MN or the SN through the UEInformationresponse message; when the MN or SN receives the SCG status information sent by the UE, it knows the SCG status change, and determines whether the PSCell on the SCG side is synchronous with the Downlink (DL) or Uplink (UL) of the network, so as to further optimize the SCG activation or deactivation decision and relevant configuration.

Fig. 2 is a second flowchart of a method for SCG status information processing according to an embodiment of the present application, as shown in fig. 2, where the method includes:

step 201, receiving state information of an SCG in a first state sent by a terminal, wherein the state information of the SCG in the first state is recorded after the terminal receives an SCG processing instruction sent by network side equipment;

step 202, determining a synchronization state of a PSCell and a network in the SCG based on state information of the SCG in a first state, and optimizing configuration of activating or deactivating the SCG;

the first state is an activated state or a deactivated state.

Specifically, at present, the terminal UE supports a multi-connection scenario. I.e. the terminal connects one MCG while connecting multiple SCGs. The MCG contains one or more cells, which are the first cell group to which the UE is connected; the MCG includes a primary cell PCell and a secondary cell SCell, where cells in the primary cell group except the primary cell are called secondary cells, and the primary cell is the first cell to which the terminal UE is connected in the MCG. The SCG comprises one or more cells, and is an added secondary cell group SCG after the UE establishes connection with the MCG, wherein the first cell connected with a terminal in all cells in the SCG is called a primary secondary cell PScell. Cells within the secondary cell group other than PSCell are also referred to as scells.

When the terminal is in a multi-connection scene, the network side equipment may send an SCG processing instruction to the terminal according to service requirements, so that the terminal adjusts the state of one or a plurality of connected SCGs, or the state of one or a plurality of SCGs to be connected is a first state, the first state comprises an activated state or a deactivated state, the state is adjusted to be different states according to different service requirements, and the terminal records and reports the state adjustment related information of each SCG.

When the terminal is in a multi-connection scene, the state of the SCG to which the PSCell currently accessed by the terminal belongs is an active state, and the PSCell and the SCG have a one-to-one correspondence relationship, and the terminal can determine the SCG to which the PSCell belongs according to the currently accessed PSCell. The currently accessed PSCell may be a target PSCell after terminal handover, where the target PSCell is a PSCell reconfigured by a network side, and an SCG to which the PSCell belongs is in an active state, or may be a source PSCell, i.e. a PSCell that is normally connected. At this time, the terminal has no service requirement, or takes energy saving into consideration, the network side sends an SCG deactivation instruction to the terminal through the master node MN or the auxiliary node SN, the terminal receives the instruction, deactivates the SCG, and records the state information of the SCG at the terminal side, namely, the terminal records the state information of the SCG in a deactivated state. The network side is favorable for knowing the SCG state change, judging whether the PScell of the SCG side is synchronous with the downlink or uplink DL/UL of the network or not, and the like, and further, the network side can be assisted to optimize the SCG activation or deactivation decision, relevant configuration and the like.

Similarly, when the state of the current PSCell to which the terminal is connected or the SCG to which the PSCell to be connected belongs is a deactivated state, the PSCell to be connected refers to a target PSCell to which the terminal needs to be switched, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in the deactivated state. At this time, since the SCG to which the target PSCell belongs is in a deactivated state, the UE does not immediately perform random access to the target PSCell. When the network side has new service requirements for the terminal and the SCG is in a deactivated state, the terminal does not monitor the PDCCH at the SCG side and does not transmit the PUSCH. It is necessary to activate the SCG to which the PSCell currently accessed by the terminal belongs as soon as possible, or activate the SCG to which the PSCell to be accessed belongs as soon as possible, and randomly access the PSCell to be accessed. The method is favorable for the quick recovery or establishment of the data transmission channel, thereby carrying out new service or data transmission. Therefore, the network side sends an SCG activation instruction to the terminal through the master node MN or the slave node SN, the terminal receives the instruction, activates the SCG, and records the state information of the SCG at the terminal side. I.e. the terminal records its state information in the active state.

The terminal records state information of the terminal in a first state, wherein the first state comprises an activated state or a deactivated state. The specific status information for recording that the SCG is in the first state may be various, for example: under the condition that an SCG activation instruction is received, recording whether the state of the SCG is an activation state or a deactivation state, and whether beam failure or radio link failure is detected in the process of activating the SCG. Under the condition that an SCG deactivation instruction is received, recording whether the state of the SCG is an activated state or a deactivated state, and whether beam failure or radio link failure is detected in the process of deactivating the SCG.

The above-mentioned recorded SCG in the first state information may be saved in the form of a new report, or recorded in the UE movement history information on the existing SCG side, or recorded in other existing reports, etc. The network device may send the above SCG activation instruction and SCG deactivation instruction to the terminal through the primary node MN or the secondary node SN.

if the network side equipment is a master node MN, the MN directly performs analysis optimization, or the MN transmits all or part of the received state information of the record SCG in a first state to an auxiliary node SN through an X2 or Xn interface, and the SN performs analysis optimization, or the MN and the SN perform analysis optimization together;

Specifically, after SCG state information is recorded, the terminal in the multi-connection scenario can report the SCG state information to a master node MN, the MN sends the received complete or partial information to an auxiliary node SN through an X2 or Xn interface, and the SN performs analysis optimization, or the MN and the SN perform analysis optimization together;

or directly sending the recorded SCG state information to the SN, and analyzing and optimizing by the SN side;

or directly transmitting the recorded SCG state information to the MN, and performing analysis optimization by the MN side.

The number of times beam failure recovery occurs, how many times beam failure recovery is performed after beam failure is detected;

step 3: the UE activates the SCG and records one or more of the following:

step 3a: the UE randomly accesses the target PSCell and records one or more of the following:

for the activation of the common SCG, the SCG activation instruction is not sent together with the synchronous reconfiguration instruction, and then the terminal needs to determine whether the network side reconfigures the target PSCell to which the terminal needs to be switched before receiving the SCG activation instruction, and the SCG to which the target PSCell belongs is in a deactivated state. If the target PSCell is reconfigured by the network side before and the SCG to which the target PSCell belongs is in a deactivated state, activating the target PSCell after receiving the SCG activation instruction, and recording the target PSCell identifier; if the target PSCell is not reconfigured at the network side before and the SCG to which the target PSCell belongs is in a deactivated state, after receiving the SCG activation instruction, activating the SCG to which the PSCell currently accessed by the terminal belongs, namely setting the SCG to which the PSCell currently accessed by the terminal belongs as an activated state.

here, the number of times the SCG is activated indicates how many times the SCG is co-activated during the UE accesses the PSCell, for example: during access to this PSCell, SCG is activated 2 times;

The duration of each SCG to be in the active state represents the duration of each SCG to be in the SCG active state at each SCG activation, for example: in the PSCell access process, the duration of the 2 times of activation is 1ms and 2ms respectively, and the duration can be correspondingly recorded in the entry of each time of activation SCG respectively;
